What are the concerns of the Physical Layer?

Physical layer coordinates the functions required to transmit a bit stream over a physical medium.a. Physical characteristics of interfaces and mediab. Representation of bitsc. Data rated. Synchronization of bitse. Line configurationf. Physical topologyg. Transmission mode

What are the responsibilities of Data Link Layer?

The Data Link Layer transforms the physical layer, a raw transmission facility, to a reliable link and is responsible for node-node delivery.a. Framingb. Physical Addressingc. Flow Controld. Error Controle. Access Control

What are the responsibilities of Network Layer?

The Network Layer is responsible for the source-to-destination delivery of packet possibly across multiple networks (links).a. Logical Addressingb. Routing
